Abstract
The increase in the prevalence of infections caused by certain bacteria, such as Klebsiella pneumonia (K. pneumoniae), is a global health concern. Bacterial production of an enzyme called extended-spectrum beta-lactamase (ESBL) can generate resistance to antimicrobial therapeutics. Therefore, between 2012 and 2013, we investigated K. pneumoniae that produce ESBLs with the prevalence of individual genes including blaSHV, blaCTX-M, blaTEM, and blaOXA isolated from clinical samples. A total of 99 variable diagnostic samples including blood from hematological malignancies (n = 14) or other clinical sources including sputum, pus, urine, and wound (n = 85) were analyzed. All samples' bacterial type was confirmed and their susceptibility to antimicrobial agents was established. Polymerase chain reaction (PCR) amplification was carried out to ascertain presence of specific genes that included blaSHV, blaCTX-M, blaTEM, and blaOXA. Plasmid DNA profiles were determined to assess significance between resistance to antimicrobial agents and plasmid number. It was found that among non-hematologic malignancy isolates, the highest rate of resistance was 87.9% to imipenem, with lowest rate being 2% to ampicillin. However, in hematologic malignancy isolates, the highest microbial resistance was 92.9% to ampicillin with the lowest rate of resistance at 28.6% to imipenem. Among collected isolates, 45% were ESBL-producers with 50% occurrence in hematologic malignancy individuals that were ESBL-producers. Within ESBL-producing isolates from hematologic malignancy individuals, blaSHV was detected in 100%, blaCTX-M in 85.7%, and blaTEM and blaOXA-1 at 57.1% and 27.1%, respectively. In addition, blaSHV, blaCTX-M, and blaOXA were found in all non-hematological malignancy individuals with blaTEM detected in 55.5% of samples. Our findings indicate that ESBLs expressing blaSHV and blaCTX-M genes are significantly prevalent in K. pneumoniae isolates from hematologic malignancy individuals. Plasmid analysis indicated plasmids in isolates collected from hematological malignancy individuals. Furthermore, there was a correlation between resistance to antimicrobial agents and plasmids within two groups analyzed. This study indicates an increase in incidence of K. pneumoniae infections displaying ESBL phenotypes in Jordan.

Extended-spectrum β-lactamase producing E. coli in urinary tract infections: A two-center, cross-sectional study of prevalence, genotypes and risk factors in Amman, Jordan. J Infect Public Health 2018; 12:21-25. [PMID: 30145152 DOI: 10.1016/j.jiph.2018.07.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 07/26/2018] [Accepted: 07/31/2018] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND To determine the prevalence, phenotypes, and genotypes of extended spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) among patients with urinary tract infection along with identifying the associated risk factors. METHODS A cross-sectional study was conducted at two tertiary hospitals in Amman, Jordan between June and October, 2016. One hundred twenty one E. coli isolates from hospitalized patients with urinary tract infection were phenotypically assessed for ESBL production using the double disc diffusion test. Positive isolates to ESBL production were further genotyped using multiplex PCR. A nested case-control study was used to determine the independent risk factors. RESULTS ESBL-producing E. coli were found in 75/121 (62%) isolates. Molecular genotyping demonstrated that CTX-M group1 (42.7%) predominated followed by combination of SHV and CTX-M group1 (20%). In the regression model, previous hospitalization and use of urinary catheter were identified as independent risk factors for ESBL-producing E. coli infections. CONCLUSION We report a high prevalence of ESBL-producing E. coli which is in concordance with other studies from developing countries. Additionally, CTX-M group1 has emerged as the predominant ESBL produced by E. coli, which is consistent with reported results throughout the world. Independent risk factors to UTI infections due to ESBL-producing E. coli include previous hospitalization and use of urinary catheter.

Abstract
Pseudomonas aeruginosa was isolated in low rates from stool specimens of outpatients and inpatients (7% versus 12%) but in higher rates from chlorinated and nonchlorinated water sources (15% versus 44%), respectively in Jordan. The same biotype was recognized among 90% of P. aeruginosa isolates from patient's stools and water sources using specific biochemical profiles. Three serogroups belonging to 01, 06 and 011 accounted for the majority of these isolates in water (66%) and stools (78%), respectively. All P. aeruginosa isolates from water were highly susceptible (87%-100%) to piperacillin-tazobactam, amikacin, gentamicin, imipenem, aztreonam, ceftazidime and ciprofloxacin, whereas the isolates from stool were slightly less susceptible (81%-98%) to these antimicrobials. P. aeruginosa isolates from water and stool sources were almost equally highly resistant to tetracycline (86%-89%) and carbenicillin (88%-89%), respectively. One common small plasmid (15.4 kb) was detected in 14/25 (56%) of multidrug-resistant P. aeruginosa isolates from both water and stool. This study demonstrates certain common epidemiological characteristics including antimicrobial resistance pattern, biotypes and serotypes among P. aeruginosa isolates from patient's stools and drinking water sources in Jordan.

Abstract
Klebsiella pneumoniae is a common hospital-acquired pathogen, causing urinary tract infections, nosocomial pneumoniae, and intra-abdominal infections. K.pneumoniae is also a potential community acquired pathogen. The aims of this study are to determine epidemiology of ESBL-producing K.pneumoniae and Koxytoca in Iran during different seasons, to determine the prevalence of blaTEM, SHV and CTX-M responsible for ESBL production among ESBL-producing K.pneumoniae and Koxytoca in the different wards and hospitals in Iraa Klebsiella spp producing ESBLs were identified by phenotypic and genotyping methods. The findings in this study revealed that 36.5%, 51.7% and 45.6% of K.pneumoniae were producing ESBLs in Ham, Milad and Emam Reza hospitals, respectively. The results revealed blaSHV was responsible for ESBLs production. The analysis showed significant difference of ESBLs production by K.pneumoniae in winter (53%) in comparison to the other seasons P≤ 0.01. The results also showed a significant difference in blaSHV that was the dominant gene responsible for ESBL production P≤ 0.049 but no significant difference was observed between blaTEM and blaSHV. The results showed that the highest ESBL production was found in Koxytoca isolated from patients in Emam Reza Hospital and the lowest frequency of ESBL production was found among Koxytoca in Ham hospital. BlaSHV was found as dominant gene responsible for ESBLs production by K.pneumoniae and Koxytoca, followed by blaCTX-M.

Abstract
Background and Objectives. Extended spectrum β-lactamase (ESBL) production is increasing all over the world, and organisms other than E. coli and K. pneumoniae are acquiring this character. ESBL production is detectable by automation, E-test, double disk diffusion (DDD), and PCR. This study aimed to determine the prevalence of ESBL production among clinical isolates of gram-negative rods, and to evaluate the effectiveness of augmentation of clavunate with Cefotaxime, Ceftazoxime, Aztreonam, Ceftriaxone, and Cefpodoxime in detecting ESBL production.
Methods. 472 clinical gram-negative isolates identified by standard methods were tested for ESBL-production by (DDD) method using six cephalosporins and amoxicillin-clavulinate discs.
Results. 108/472 (22.9%) of the isolates were ESBL producers, and were prevalent in tertiary care hospitals. 88.2% of E. cloacae, 71.4% of K. pneumoniae, 28.6% of K. oxytoca, 12.5% of C. freundii, 11.1% of A. calcoacceticus, and 10.8% of E. coli were ESBL producers. The DDD test demonstrated some variations in the efficacy of the different cephalosporins in detecting all the ESBL producers. The inclusion of ceftizoxime discs increased the efficacy of the test. It is concluded that ESBL-producing bacteria were prevalent among our hospitalized patients, and involved genera other than Klebsiella and Escherichia, and the inclusion of ceftizoxime increased the efficacy of ESBL detection by the DDD test.

Abstract
BACKGROUND AND OBJECTIVES Reports on extended-spectrum beta-lactamases (ESBL) production by Enterobacteriaceae, and especially in Klebsiella pneumoniae, are few in Saudi Arabia. Therefore, we determined the prevalence of ESBL in K pneumoniae from Riyadh and characterized the predominant beta-lactamase gene in these isolates. METHODS A total of 400 K pneumoniae samples were isolated from two hospitals in Riyadh during 2007 and screened for production of ESBL using ESBL-E-strips and combined disk methods. PCR assay was used to detect bla(TEM), bla(SHV), and bla(CTX-M) genes. RESULTS Phenotypic characterization identified a high ESBL rate of 55% of K pneumoniae isolates. ESBL producing K pneumoniae were PCR positive for SHV, TEM and CTX-M beta-lactamase genes with prevalences 97.3%, 84.1% and 34.1%, respectively. Within the CTX-M family, two groups of enzymes, CTX-M-1 and CTXM- 9-like genes were found with prevalences of 60% and 40%, respectively. CONCLUSIONS This study confirms the high rate of ESBL in K pneumoniae clinical isolates in hospitals in Riyadh. This study demonstrates the worldwide spread of bla(CTX-M) genes. This first report of the presence of the bla(CTX-M) gene in clincial isolates in Saudi Arabia is evidence of the continuing worldwide spread of this gene.

Abstract
Peritonitis is not an infrequent complication of inpatients with chronic ambulatory peritoneal dialysis (CAPD). CAPD peritonitis may be related to the catheter or secondary to perforation of an intra-abdominal viscus. The most common organisms usually associated with CAPD peritonitis are Staphylococcus aureus and Staphylococcus epidermidis (coagulase-negative staphylococci). Rarely, aerobic gram-negative bacilli have been the causative agents of CAPD peritonitis. The treatment of CAPD peritonitis usually requires removal of the peritoneal catheter and treatment with parenteral antibiotics active against the causative pathogen. We report a case of CAPD-associated peritonitis caused by an extended spectrum beta-lactamase-producing strain of Klebsiella pneumoniae. The case presented had this strain of multidrug-resistant K. pneumoniae present in blood cultures and the peritoneal fluid. Extended spectrum beta-lactamase-producing bacteria, for example, K. pneumoniae, are multidrug-resistant and sensitive to few antibiotics. This isolate was intermediately sensitive to amikacin and meropenem, but the patient did not clinically improve on these 2 antibiotics. Polymyxin B therapy was initiated after lack of clinical improvement after dialysis catheter removal and 1 week of meropenem and amikacin therapy. The patient responded rapidly to therapy with polymyxin B. Polymyxin B has a unique mechanism of action on bacterial cells and is highly active against all multidrug-resistant gram-negative organisms except Proteus species and Serratia marcescens. No toxicity was observed during therapy. Polymyxin B is being used increasingly as a therapeutic alternative to multidrug-resistant gram-negative organisms.

Abstract
Nosocomial pneumonias are recognized as an important cause of morbidity and mortality in industrialized nations. Emerging data show that they play a similar role in the developing world. A host of extrinsic and intrinsic factors predispose individuals to the development of pneumonias, and a modification of some of these factors provides a low cost solution to prevention of pneumonias. The ideal modality for microbiologic diagnosis of pneumonia remains to be determined. Recent data suggest that there is no difference in outcome when noninvasive techniques are compared with invasive techniques. Antimicrobial resistance is a rapidly increasing problem globally, and combating this with appropriate antibiotic policies, close surveillance, and physician education is essential.
